That’s when things got even more crazy. Dave said I can do better than that. I asked what do you mean and he said I’ll fuck him to which the girls...yelled hell yes it’s always fun to watch them. I couldn’t believe what I just heard but after all this nothing was surprising anymore. Here I was going to watch my son fuck another man and I was getting wet.Kim had brought out the lube so when Jim got on his knees Dave poured it down his crack and rubbed his cock with it. I couldn’t take my eyes off. I look you right in the eyes and SMACK, right across your face. It hurts but you know you deserve it for being such a fat pig. I spread your giant thighs and finally find your cunt in all those folds. You're wet because you are so excited anyone would even pay attention to you.I jam 4 fingers up your cunt and fist fuck you a bit. Then I shove my fist in your mouth deeper and deeper until you choke on it. SMACK across your face again. I grab your hair and force you to your knees. Pull open your.

Nothing even remotely sexy had ever occurred with him prior to that Summer.I may have stared at it his red penis when it showed out, but more in curiosity as it just looked so different but I never once dreamed of touching it, the very thought of it would have.
